Coproduction of Geothermal Power from Oil and Gas Fields in CaliforniaHot water produced from oil and gas wells can be used to generate geothermal power under certain temperature and flow conditions. This report provides links to technical reports about produced water and reservoir temperatures from oil and gas fields in California. Links to electric logs and to information on temperature gradients in sedimentary basins within the State are also provided.
